    Multiple vulnerabilities have been discovered in PostgreSQL. Please
      review the CVE identifiers referenced below for details.
  
Impact :

    A remote attacker could possibly execute arbitrary code with the
      privileges of the process, bypass certain client-side connection security
      features, read arbitrary server memory, alter certain data or cause a
      Denial of Service condition.
  
Workaround :

    There is no known workaround at this time."
